Description
Technical Field
The utility model relates to a coal fired power plant waste water treatment environmental protection technology, concretely relates to rotatory atomizing drying system of jam is prevented to waste water emission reduction.
Background
The limestone gypsum wet flue gas desulfurization device of the coal-fired power plant can generate desulfurization waste water in the operation process, the suspended substance and salt content of the waste water are high, the heavy metal content also exceeds the national discharge standard, and if the waste water is directly discharged, serious pollution can be caused to a receiving water body. The 'implementation scheme for controlling pollutant emission permission' which comes out in 2016, 11, 10 clearly indicates that the emission permission of the thermal power industry enterprises is approved, so that the treatment of the desulfurization wastewater of the coal-fired power plant becomes a key research object for all professionals in the industry.
In order to respond to the increasingly strict environmental protection policy of China, the modification of the desulfurization wastewater zero-discharge process of the coal-fired power plant becomes a trend. The existing treatment process route of the desulfurization wastewater is pretreatment, concentration and decrement and tail end curing technology, and a bypass flue evaporation curing process, so that the operation cost can be reduced by using the waste heat of flue gas, and most of salt in the wastewater is mixed into fly ash after being dried and cured to realize zero emission, thereby becoming a hot tail end curing technology.
The bypass flue evaporation and solidification process comprises two forms of rotary atomization and double-fluid atomization, and the two processes have advantages and disadvantages when operated on site, and the optimal scheme is the best scheme by selecting proper technology according to local conditions. The working principle of rotary atomization is that a motor of a rotary atomizer drives a rotary atomizing disc to rotate at a high speed, so that desulfurization liquid is dispersed into fine liquid drops, and the fine liquid drops enter a desulfurization tower in a bowl-shaped spray shape to transfer heat and mass with flue gas. In the operation of the desulfurization device, in order to prevent the material corrosion of the desulfurization device and ensure the stable and efficient operation of the system, the concentration of chloride ions in the slurry is generally maintained at 12000-20000 mg/kg, and the density of the slurry is generally controlled at 1075-1150 kg/m3Therefore, a certain amount of slurry must be discharged from the desulfurization unit, and the higher the chloride ion concentration out of range entering the desulfurization tower, the more slurry is required to be discharged, and the larger the amount of wastewater generated.
In the solidification process, in order to prevent the corrosion of acid components to subsequent equipment when the temperature of the flue gas is reduced and ensure that hydrogen chloride in the wastewater cannot enter the flue gas again under the acid condition, a certain amount of alkali liquor such as slaked lime slurry or sodium hydroxide solution and the like is added into the wastewater (namely, the pH value of the wastewater is controlled to be more than 9), so that the alkali liquor and the wastewater are atomized together, and the acid components of the flue gas are absorbed by alkaline fog drops in the contact process of the alkali liquor and the flue gas. However, the desulfurization waste water added with alkali liquor is easy to cause abrasion of the rotary atomizing disc, and can start to block along with the increase of time, the abrasion and the blocking can cause the atomizing wheel rotating at high speed to be damaged in an accelerating way, and the rotary atomizer can be stopped and overhauled when the abrasion and the blocking are serious. In addition, the power plant can not run at full load for a long time under most conditions, and sometimes can run at medium and low loads, under the condition, the amount of high-temperature flue gas which can be extracted in front of the air preheater is limited, the provided heat can not meet the design index of full-load operation, and a series of problems such as partial waste water consumption are caused.
